Earlier this year, Josh admitted to inappropriately touching underage girls, including his sisters, when he was a teenager. Then in August, he admitted to being "unfaithful" to his wife after he was linked to paid Ashley Madison accounts. On Aug. 26, it was confirmed that he had checked into a treatment center to seek help.

While it might take some time before Josh is completely accepted back into the fold, a source told ET this past week that certain members of the Duggar family have been writing encouragement cards to the Jim Bob and Michelle’s eldest son, and sending him their forgiveness.

However, in August, Jessa publicly sided with her father-in-law, Michael Seewald, who condemned Josh in a blog post for being "a pretender" who sinned against God.

"It distresses me to say that Josh Duggar’s greatest sin is a byproduct of the sum total of his secretly sinful lifestyle. That is, that by his hypocrisy, he blasphemed the name of God. He claimed to be a Christian, but by his deeds he has suggested otherwise," he expressed in the lengthy post, which he says he wrote because of "an overwhelming desire to vindicate the name of God."

It's not known if Jessa is one of the family members who is writing to Josh, but whatever her feelings are towards her sibling, it certainly hasn't stopped her from seeing her niece.
